It is a binder composition for non-aqueous secondary batteries containing the particulate-form polymer containing the block copolymer A represented by the following general formula (A). Ar1 a -D a -Ar2 a ...(A) [Here, in the general formula (A), Ar1 a represents a block region comprising aromatic vinyl monomer units having a weight average molecular weight of 5,500 to 20,000, and Ar2 a is an aromatic vinyl having a weight average molecular weight of 40,000 to 400,000 A block region composed of a monomer unit is shown, and D a represents a block region composed of an aliphatic conjugated diene monomer unit.] |
